SEWING-MACHINE HEAD.

Specification of Letters l atent.

Patented Feb. 1?, 1914.

Application filed March 13, 1912. Serial No. 683,428.

To all whom it may concern Be it known that I, ALICE G. CooPER, acitizen of the United States, and a resident of San Diego, in the countyof San Diego. and State of California, have invented certain new anduseful ing-Machine Heads, is a specification.

- My invention relates to a scale or guide on the top surface of the bedplate of a sewing and the objects of my invention, are, to provide ascale readily visible to the operator of a sewing machine, to gage thedistance of the seam from the edge. of the cloth or the width of hemsand the like, and to provide a means to facilitate a uniformity in seamsand the like and further to provide a ready means for measuring thewidth thereof.

With these and other objects in 'view as will appear, my inventionconsists in certain novel features .of construction. combination andarrangement of parts as will be hereinafter described in detail andparticularly set forth in the appended claim,reference beingImprovements in Sewof which the following had to the accompanyingdrawings and to .I

the characters of reference thereon, which form a part of thisspecification, in which Figurel is a perspective view of a sewingmachine head, showing my preferred construction, Fig. 2 is a similarView of the same showing a scale placed on a sewing machine head in amodified form from that shown in Fig. 1, and Fig. 3 is a perspectiveview of the scale plate.

Similar characters of reference refer to similar parts throughout theseveral views.

. In the drawings, numeral 1 represents the bed plate of the sewingmachine head, 2 the arm, 3 the needle plate, 4 the front slide, 5 theback slide and 6 the scale plate. The sewing machine head is of theordinary'type, except that the needle plate 8 is provided with a scalestarting at the needle hole therein and the inner ends of the slides 4and 5 are provided with a continuation of said scale. Inserted in thebed plate 1 is'my scale plate 6 bed plate 1, and it is provided on itsupper surface with a continuation of the scale upon the slides 4 and 5.,

In my modified construction, instead of inserting a plate 6 for the,scale, the scale is which is preferably set into the Y simply placeddirectly onthe upper surface of the bed plate, continuing the scale onthe slides 4 and 5.

Though I have shown and described particular methods of placing a scaleon sewing machine heads, I do not wish to be limited to this particularconstruction, but desire to include in the purview of my. invention, theplacing of a scale, starting at the needle hole in the needle plate andextending some dis tance toward the arm connection, substan- 65 tiallyas set forth in the appended claim.

It will be readily seen that with this scale, the determining and mainaining of the width and uniformity of seams, hems and the like will begreatly facilitated.

Having thus described my invention, what ters Patent is v In a sewingmachine the combination of a needle plate, provided with ascale-starting at the needle hole therein and extending to the outeredge longitudinally with the bed plate of the machine, front and rearslides contiguous to said needle plate provided with a continuation ofsaid scale on their inner ends and a plate detachably mountedlongitudinally with the bed plate of the machine provided with acontinuation of said scale upon said slide.

claim as new and desire tosecure by Let- In testimony whereof, I havehereunto subscribed my name in subscribing witnesses.
